Newport MKS Vibration Isolator Set, Six 28 in. S-2000A Pneumatic Isolators S-2000A-628

The S-2000A-628 Stabilizer Set includes (6) 28 inch isolators and is supplied with the leveling valve set, that includes (3) valves, connectors, tubing and other accessories that are required for installation. These isolators incorporate enhanced leveling indicators, recessed lifting channels and a significantly lower magnetic permeability Aluminum casting construction which greatly improves the ease of use. The 8000 lb total load capacity is an ideal solution for isolating optical tables, large inspection equipment, and heavy machinery. S-2000 Stabilizer™ Pneumatic Vibration Isolator Overview Stabilizer™ Hybrid Chamber Design One of the most important design goals of pneumatic vibration isolator is to achieve lower natural frequency. It is related to the isolator's compliance volume - the larger the volume, the lower the frequency. Unlike the conventional design of a compliance chamber (the volume of which affects natural frequency) and a damping chamber, Newport's patented Stabilizer hybrid chamber design consists of a small size initial chamber and a second damping chamber together as a unified hybrid chamber. Because the initial chamber is reduced dramatically in size, it forces the isolator to use the second chamber as part of the compliance volume, which greatly increases the compliance volume for a given package size, and greatly lowers the natural frequency. Trifilar Pendulum Design for Horizontal Isolation The S-2000's superior horizontal isolation is achieved through a mechanical filter system. Compared with other manufacturers' contacting bearing surfaces, Newport introduces zero friction trifilar pendulum system emerged in energy dissipating oil to eliminate the friction that commonly disturb high accuracy applications, thus enabling isolation to much lower vibration levels as well as high accuracy table repositioning after disturbances. In addition, the S-2000 design features proprietary self centering capability, to better ensure isolator alignment and eliminate horizontal shorting which could happen in other designs. Laminar Flow Technology Boosts Damping Efficiency Apart from low natural frequency, another indicator of the isolator performance is damping efficiency. It is proportional to the air flow and pressure drop through the damper. Newport's exclusive incorporation of laminar flow damping element in the isolator design largely improves the damping efficiency compared to competitor's single orifice or thin tube design. The laminar flow disks connecting the two chambers create better linkage between piston motion and damping chamber air flow. This generates a higher damping force for a given piston displacement for faster, more efficient damping. It also lowers the amplification at resonance and improves isolation bandwidth and settling time. S-2000A also uses custom molded ultra-soft diaphragms to reduce the stiffness to further improve the vertical isolation performance. Fast and Easy Installation Installation is fast and easy with patented, self-centering pistons. They automatically center the piston at the top and bottom of its vertical stroke, guaranteeing unrestricted movement for optimal performance. SafeLock™ mounting brackets eliminate the need to precisely align isolators and table holes when attaching the isolator to the table. Mechanical height adjustment allows quick and easy table leveling and compensates for non-level floors. Built-in leveling indicators provide visual feedback ensuring the table is properly floating at the correct level.
